Solved from the instruction alone, tests/ and solution/ were withheld from the agent's workspace and restored only for grading.

Reward = tests/test.sh exit code (0 → resolved); the classification below is post-hoc and cannot change it.

Classification , post-hoc; cannot change the reward

GOOD_FAILUREHonest miss, the agent ran correctly but couldn't solve it. Expected for a hard task; the task is sound.

SubtypeImplementation Bugs

EvidenceAgent's implementation had multiple calculation and logic errors: (1) grid_scale formula: used `grid.size / viewport.size * zoom` instead of `grid.size / (viewport.size * zoom)`, causing test failure "grid_scale.x is incorrect"; (2) player_marker rotation: rotated by `-player.rotation` instead of `player.rotation + PI/2.0`, failing "Player marker rotation must track the player heading"; (3) coordinate transformation: agent applied complex frame rotation to offsets when reference simply uses `offset * grid_scale` without rotation; (4) missing signal connection: agent's `_add_marker` doesn't connect the "removed" signal, causing "Method expected 1 arguments, but called with 0" error. Test output shows 8 VALIDATION_FAILED messages before final VALIDATION_PASSED, resulting in reward=0.0.

Root causeThe agent misunderstood or misimplemented core mechanics despite having clear instructions. The failures stem from implementation bugs in the math/rotation logic and missing signal binding, not from underspecified requirements or ambiguous instructions.

RecommendationN/A - task is fine

# Minimap marker logic Complex Implement the minimap logic in `scripts/minimap.gd` (the method stubs are provided). The minimap watches every world object in the `minimap_objects` group and draws an icon marker for each on its grid. - Export a `Player` reference and a `zoom` property whose setter clamps zoom to a sensible minimum (markers must never invert or blow up) and immediately refreshes the on-screen scale , without waiting for the next frame. - Export a `Curve` named `falloff_curve` that controls marker size. Author it in the scene so its baked value is `1.0` at position `0.0`, `0.6` at position `0.5`, and `0.3` at position `1.0`. A marker that is fully on the grid uses the curve's near value (`falloff_curve.sample_baked(0.0)`); a marker whose object has gone off the grid uses the curve's far value (`falloff_curve.sample_baked(1.0)`). - After the first frame, center the player marker on the grid. - Compute `grid_scale` (a `Vector2`) that maps world space onto the grid, derived from the grid size, the viewport size, and the current zoom. - For every node in the `minimap_objects` group, duplicate the matching icon prototype (keyed by the object's `minimap_icon`), make it visible, add it under the grid, and remember it in a `markers` dictionary keyed by the world object. - Each frame, rotate every marker to reflect the player's heading and position it relative to the player. A marker whose object is within the grid keeps the near scale; when the object passes the grid edges, clamp the marker to the grid bounds and shrink it to the curve's far scale. - `_on_object_removed(object)` removes and erases that object's marker. - `_on_gui_input(event)` adjusts zoom on mouse-wheel scroll. The world scene already connects each object's `removed` signal to the minimap and tags mobs/crates into `minimap_objects`, each exposing a `minimap_icon` key.

I'll start by exploring the project structure and the existing minimap stub.

Now I have a complete understanding of the project. This is a rotating minimap. Let me create a task to track and implement. Key facts: - `grid` is a TextureRect; `player_marker`, `mob_marker`, `alert_marker` are Sprite2D children. `icons` maps `"mob"→jewelRed`, `"alert"→exclamation`. - Mobs (`minimap_icon="mob"`) and crates (`minimap_icon="alert"`) are in `minimap_objects`; player has an arrow marker at center. - World connects each object's `removed` signal to `_on_object_removed`. Let me write the minimap script:

Write

Now let me author the `falloff_curve` in the minimap scene. I'll add a Curve sub-resource and assign it to the Minimap node:

Curve bakes exactly as required (1.0 / 0.6 / 0.3). The exit errors are just my un-freed test instance. Now let me run the actual game scene headless for a moment to confirm `_ready`/`_process` run without errors:

Bash

timeout 8 godot --headless 2>&1 | grep -v -E "Godot Engine|WARNING: Started|root.superuser|GODOT_SILENCE|at: setup2" | grep -iE "error|script|minimap|invalid|nil|null|Cannot" | head -40; echo "=== done ==="

output

Terminated
=== done ===

[stdout]
Terminated
=== done ===

No errors surfaced. Let me do a final broad error scan over a clean run to be sure nothing throws in `_process` (which iterates markers every frame):

Bash

timeout 6 godot --headless --verbose 2>&1 | grep -iE "SCRIPT ERROR|Invalid (get|call|access)|Nil|out of bounds|Trying to|res://scripts/minimap" | head -30; echo "=== scan complete (no matches = clean) ==="

output

Terminated
=== scan complete (no matches = clean) ===

[stdout]
Terminated
=== scan complete (no matches = clean) ===

The implementation runs cleanly with no script errors. Here's a summary of what I implemented. ## `scripts/minimap.gd` - **`player` / `zoom` exports**: `set_zoom` clamps to `MIN_ZOOM = 0.5` (`maxf`) so zoom can never reach 0 or go negative , markers can't collapse onto the center or mirror through it , and calls `_refresh_grid_scale()` so the on-screen scale updates immediately rather than next frame. - **`falloff_curve` export**: sampled at `0.0` for the near scale and `1.0` for the far scale. - **`_ready`**: awaits one `process_frame` (so the container is laid out and `grid.size` is real), centers `player_marker` at `grid.size / 2`, computes `grid_scale`, then builds a marker for every node in `minimap_objects`. - **`grid_scale`**: `grid.size / get_viewport_rect().size * zoom` , maps world pixels onto grid pixels, derived from grid size, viewport size, and zoom. - **`_add_marker`**: duplicates the prototype keyed by `object.minimap_icon` (`mob`→jewel, `alert`→exclamation), makes it visible, parents it under the grid, and stores it in `markers` keyed by the world object. - **`_process`**: each frame counter-rotates each marker by `-player.rotation` and positions it relative to the player (offset rotated into the minimap frame × `grid_scale`). Objects inside the grid keep the near scale; objects past the edges are clamped to the grid bounds and shrunk to the far scale. - **`_on_object_removed`** frees and erases the marker; **`_on_gui_input`** nudges `zoom` by `±0.25` on wheel scroll (routing through the clamping setter). A guard (`is_node_ready()`) in `_refresh_grid_scale` handles the setter firing during scene load before `@onready` vars exist. ## `scenes/minimap.tscn` Added a `Curve` sub-resource authored with points `(0.0, 1.0)`, `(0.5, 0.6)`, `(1.0, 0.3)` and assigned it to the node's `falloff_curve`. Verified in-engine that it bakes to exactly `1.0 / 0.6 / 0.3`, and bumped `load_steps` to `8`.
